Wayne E Thogmartin, PhD
I am a quantitative ecologist conducting scholarly research at the intersection of animal ecology, spatial analyses, and statistics.
My interests are in population ecology for animals declining in abundance, asking new questions of multiple, combined data sets to gain novel insight into the dynamics of animal populations, and translating science into guidance for practical management decisions.

Pesticides and pollinators: A socioecological synthesis
The relationship between pesticides and pollinators, while attracting no shortage of attention from scientists, regulators, and the public, has proven resistant to scientific synthesis and fractious in matters of policy and public opinion. This is in part because the issue has been approached in a compartmentalized and intradisciplinary way, such that evaluations of organismal pesticide effects reAuthorsDouglas B.

Thogmartin, Neal M. Williams, Minghua Zhang, Margaret R. DouglasEstimating uncertainty of North American landbird population sizes
An important metric for many aspects of species conservation planning and risk assessment is an estimate of total population size. For landbirds breeding in North America, Partners in Flight (PIF) generates global, continental, and regional population size estimates. These estimates are an important component of the PIF species assessment process, but have also been used by others for a range of aAuthorsJessica C. Stanton, Peter J. Blancher, Kenneth V. Rosenberg, Arvind O. Panjabi, Wayne E. ThogmartinEcosystem service flows from a migratory species: Spatial subsidies of the northern pintail
Migratory species provide important benefits to society, but their cross-border conservation poses serious challenges. By quantifying the economic value of ecosystem services (ESs) provided across a species’ range and ecological data on a species’ habitat dependence, we estimate spatial subsidies—how different regions support ESs provided by a species across its range. We illustrate this method foAuthorsKenneth J. Bagstad, Darius J. Semmens, James E. Diffendorfer, Brady J. Mattsson, James A. Dubovsky, Wayne E. Thogmartin, Ruscena Wiederholt, John B. Loomis, Joanna A. Bieri, Christine Sample, Joshua Goldstein, Laura Lopez-HoffmanMulti-country willingness to pay for transborder migratory species conservation: A case study of Northern Pintails
Using contingent valuation, we estimated willingness to pay (WTP) in Canada, Mexico, and the United States to protect habitat for Northern Pintails (hereafter pintails), a migratory waterfowl species that provides benefits to and requires habitat in the three countries. Our study contributes to research on spatial subsidies by measuring the value of migratory species habitat. While WTP to protectAuthorsMichelle Haefele, John B. Loomis, Aaron M. Lien, James A.

Diffendorfer, Laura Lopez-HoffmanAccounting for surveyor effort in large-scale monitoring programs
Accounting for errors in wildlife surveys is necessary for reliable status assessments and quantification of uncertainty in estimates of population size. We apply a hierarchical log-linear Poisson regression model that accounts for multiple sources of variability in count data collected for the Integrated Waterbird Management and Monitoring Program during 2010–2014. In some large-scale monitoringAuthorsKevin Aagaard, James E. Lyons, Wayne E. ThogmartinDo economic values and expenditures for viewing waterfowl in the U.S. differ among species?
Many economic studies value birdwatching in general and often do not account for potential differences in viewers’ benefits from observing different species. But, how different are economic values of viewing various bird species? To answer that question, we surveyed Ducks Unlimited (DU) members using an online questionnaire to estimate trip expenditures and consumer surplus per trip for viewing piAuthorsJohn Loomis, Michelle Haefele, James Dubovsky, Aaron M.

Semmens, Laura Lopez-Hoffman, Robert MeridethQuantifying ecosystem service flows at multiple scales across the range of a long-distance migratory species
Migratory species provide ecosystem goods and services throughout their annual cycles, often over long distances. Designing effective conservation solutions for migratory species requires knowledge of both species ecology and the socioeconomic context of their migrations. We present a framework built around the concept that migratory species act as carriers, delivering benefit flows to people throAuthorsDarius J. Semmens, James E. Diffendorfer, Kenneth J.

Telemetry data for 59 Northern Leopard Frogs (Lithobates pipiens) breeding in ponds in Houston and Winona Counties, MN; 2001-2002. Agricultural intensification is causing declines in many wildlife species, including Northern Leopard Frogs (Lithobates pipiens). Specific information about frog movements, habitat selection, and sources of mortality can be used to inform conservation-focused land manaAuthorsMelinda G. Knutson, Jennifer H. Herner-Thogmartin, Wayne E. Thogmartin, Joshua M. Kapfer, John C. NelsonModeling the relationship between water level, wild rice abundance, and waterfowl abundance at a central North American wetland
Recent evidence suggests wild rice (Zizania palustris), an important resource for migrating waterfowl, is declining in parts of central North America, providing motivation to rigorously quantify the relationship between waterfowl and wild rice. A hierarchical mixed-effects model was applied to data on waterfowl abundance for 16 species, wild rice stem density, and two measures of water depth (trueAuthorsKevin Aagaard, Josh D. Eash, Walt Ford, Patricia J. Heglund, Michelle McDowell, Wayne E. ThogmartinSlow and steady wins the race? Future climate and land use change leaves the imperiled Blanding's turtle (Emydoidea blandingii) behind
Climate change is accompanied by shifts in species distributions, as portions of current ranges become less suitable. Maintaining or improving landscape connectivity to facilitate species movements is a primary approach to mitigate the effects of climate change on biodiversity. However, it is not clear how ongoing changes in land use and climate may affect the existing connectivity of landscapes.AuthorsChristopher M. Hamilton, Brooke L. Bateman, Jessica M. Gorzo, Brendan Reid, Wayne E. Thogmartin, M. Zachariah Peery, Patricia J. Heglund, Volker C. Radeloff, Anna M. PidgeonTemperature-influenced energetics model for migrating waterfowl
Climate and weather affect avian migration by influencing when and where birds fly, the energy costs and risks of flight, and the ability to sense cues necessary for proper navigation. We review the literature of the physiology of avian migration and the influence of climate, specifically temperature, on avian migration dynamics.

Many metrics exist for quantifying the relative value of habitats and pathways used by highly mobile species. Properly selecting and applying such metrics requires substantial background in mathematics and understanding the relevant management arena. To address this multidimensional challenge, we demonstrate and compare three measurements of habitat quality: graph-, occupancy-, and demographic-basAuthorsJoanna A. Bieri, Christine Sample, Wayne E.
